A method of assembling a nozzle assembly is disclosed. The method includes: providing a nozzle member having a central passage defined by at least an inner side surface and an inner distal surface; inserting a fluid atomizer into the central passage of the nozzle member; and, with a distal surface of the fluid atomizer arranged adjacent the inner distal surface of the nozzle member, flexing legs of the fluid atomizer in a radially-outward direction for engaging each leg of the legs with the inner side surface of the nozzle member. A fluid atomizer is also disclosed. A nozzle assembly is also disclosed. A method of utilizing a nozzle assembly is also disclosed.

A rain simulation system that replicates realistic raindrop characteristics for controlled testing is invented. The rain simulation system can be used as a stand-alone system with wind using a blower fan or in a wind tunnel, and without wind to create wind-driven and vertically falling rain droplets, respectively. In addition, methods to simulate rainfall for stationary and moving objects such as a road passenger vehicle are proposed. The rain simulation system is fully adjustable for a range of droplet size, impact velocity, rain intensity, rain coverage via the use of dripping nozzle devices and positioning of system components. The rain simulation system dispenses distinct droplets or continuous streams that can be broken down into droplets by wind. A rain nozzle device is coupled with a rain reservoir, and multiple nozzles are used to create a rain matrix, the full matrix is integrated with a rain rack and rainwater flow control strategy.

A walk from behind, also called a push or cart sprayer having an assembly of wheeled frame and a tank. The frame has a rearward extending handle which enables the assembly to be pushed along a path. The tank has a connected boom assembly including a pivotal boom arm along the front of the tank with a distal spray nozzle, and a mechanism enabling the boom arm to be pivoted to the sides of the tank where the nozzle sprays away from the path, to the side of the path, so that possible toxic or corrosive spraying liquid cannot be stepped upon by the operator pushing the sprayer, thereby enhancing safety of operation. The boom arm is also pivotal to the front of the tank, such as useful when the cart sprayer is towed.

A fluid dispenser comprising:

a reservoir (1);

a dispenser head (T) that is provided with a dispenser orifice (62);

a dip tube (22) that conveys the fluid from the reservoir (1) to the dispenser head (T);

a pusher (6) that is axially movable over a determined stroke;

an electric pump (4) that delivers air into the reservoir (1) so as to force the fluid through the dip tube (22) as far as the dispenser head (T), the electric pump (4) being actuated by the pusher (6); and

a fluid outlet valve (7);

the fluid dispenser being characterized in that:

all of the air coming from the electric pump is delivered into the reservoir;

the electric pump (4) is activated by the pusher (6) as soon as it leaves its high rest position, and the outlet valve (7) is opened only in the proximity of the low depressed position, such that the electric pump (4) is electrically powered well before the outlet valve (7) is opened; and

the electric pump (4) delivers air into the reservoir (1) with an increase in pressure that is less than 1 Bar.

A siphon-type airbrush, comprising a front handle, a tail handle, a needle, a sprayer, a nozzle, an air inlet valve and a nozzle base; the front handle corresponds to the tail handle to form an airbrush body; the airbrush body is internally formed with an accommodating cavity; the accommodating cavity is internally provided with the needle; the front handle is internally provided with a siphon channel; the air inlet valve is disposed at the middle part of the airbrush body; the rear end of the nozzle base is in threaded connection with the front handle; the front end of the nozzle base is in threaded connection with the sprayer; the nozzle comprises a nozzle body; the nozzle body is pressed between the sprayer and the nozzle base; the front end of the nozzle body extends to form a nozzle tip.

A cleaning device is provided. The cleaning device comprises a hollow, hand-held wand that accepts pressurized gas at a first end and forces the gas out a second end, a trigger mechanism that features a coupling for acceptance of gas from a hose positioned at the first end, and a diffuser attached perpendicularly to the second end to receive and release the pressurized gas, the diffuser disposed to turn in a spinning motion, whereby ends of the diffuser are angled and feature one slit opening per end, and whereby the angled ends facilitate the spinning motion by the diffuser.

An undercarriage washing assembly includes a base that may be rolled along a support surface. Thus, the base may be rolled beneath an undercarriage of a vehicle. A plurality of wheels is provided. Each of the wheels is rotatably coupled to the base to roll along the support surface. A handle is movably coupled to the base. A spray unit is coupled between the handle and the base. The spray unit may be coupled to a fluid source to deliver a fluid onto the undercarriage thereby facilitating the undercarriage to be cleaned. The spray unit includes a reservoir. The reservoir may contain a detergent thereby facilitating the spray unit to deliver the detergent to the undercarriage.

A holder assembly includes a pole has an upper section and a lower section. An engaging member is coupled to the upper section. The engaging member may retain a paint gun on the pole. A connector is coupled to the pole such that the connector is positioned proximate a distal end of the pole with respect to the engaging member. A trigger is movably coupled to the connector. A cord extends between the paint gun and the trigger. The trigger may actuate the paint gun when the trigger is actuated.

A two part airless adhesive spray system is provided herein. This system provides numerous enhancements to the prior art including limiting overspray “fog,” saving on sprayed material because of a more efficient spray pattern, and providing a stronger bond than that of the air-atomized spray guns of the prior art.

A shower system includes an inlet configured to receive water from a supply conduit and a plurality of spout outlets configured to discharge water from the shower system. A diverter is configured to receive water from the inlet and deliver water to the plurality of spout outlets, and the diverter is actuatable to change a water discharge mode of the plurality of spout outlets. A valve is configured to receive water from the inlet, and the valve is actuatable to a first position and a second position. A diverter actuator is configured to receive water from the valve in the second position. The diverter actuator is actuatable from an unactuated position to an actuated position upon receiving water from the valve, and the diverter actuator thereby actuates the diverter to change the water discharge mode of the plurality of spout outlets.
